This application is a continuation-.impart of Application Serial No.594,701, filed May i9, 1945, for Smokers Articles, which application isnow abandoned.

The pipe disclosed herein comprises a metal, dished bowl holder .2Sprovided with a bowl supporting portion 22 which in the embodiment shownis dished, being provided with an upper threaded portion 211 anda lowercondensing plug or dome 2E, which preferably is disposed on the centerlineof the bowl 428 at the lowest point thereof. cylindricalor'frusto-Corlical, is re-entrant and is preferably cast integral withthe bowl holder. The plug 26 being reeentrant, is open at the bottornthereofk tothe atmosphere and projects upwardly Within the bowlv holder2B. Therefore, when the bowl 28 'i's" in place, as shown in Figure Saidplug, as shown, is substantially l, there is a relatively large coolingsurface adjacent the bottom of the bowl, as the plug extends upwardlywithin the holder and the top 29 of the plug forms a portion of thebottom of the bowl. Thus the major portion of the condensing takes placein the main trap portion 30 between the bottom wall 3i of the bowl 26and the bowl holder 2U. Wall 3| of the bowl 28 is preferably dished orshaped in a manner to substantially conform to the shape of the bowlholder, so that when the bowl is in position as shown in Figure 3, thetrap portion 30 is of substantial magnitude. The bowl 28 is providedwith corresponding threads 32 for securing the bowl to the threads ofthe threaded portion 24, it 'being understood, of course, that a pressor other llt may be used. i Y

In the construction shown the threads of the metal bowl holder aremetal, while the material of the mating threads of the bowl are ofdifferent material such as wood, corn-cob and the like, depending uponthe material from which the bowl and its threads are formed, and becauseof the diierence in material between the mating threads of the holderand bowl there is no tendency for galling of the threads. Further, inthe construction shown even though there is. a relatively short lengthof thread, a quadruple thread is provided which makes it possible toentirelyset the bowl by a quarter turn of the bowl, and in additiongives four entrances to the thread of the bowl, and as a multiple threadprovides a construction of lesser mechanical advantage than a singlethread for the same thread length, the present construction eliminates apossibility of too tightly setting the bowl on the body. It isunderstood that while four threads are used, the optimum number ofthreads is determined by the thread running length, which in theconstruction shown amounts to four threads.

The tobacco receiving portion or recess 34 of the bowl terminates in anopening or aperture 36 which is of similar shape (shown substantiallycylindrical) to the condenser plug 26, and when the .bowl is fastened tothe holder, in its operative position, the plug preferably extendswithin the aperture 36 and is flush with the bottom of the bowl. Theplug is of slightly less diameter than the diameter of the opening 36and thus a small peripheral opening 38 is provided which prevents theentry of tobacco into the holder, though the opening 38 actually is ofsubstantially the same area as that of the ordinary draw hole in aconventional pipe.

In its operative position the bottom wall 3l of the bowl is preferablyarcuate or of substantially the same shape as the bowl holder, the wall3l, when the bowl is in position as shown in Figure l being slightlyspaced from the dished supporting portion 22, forming the main trap 30for moisture, condensate and the like, it being understood of coursethat a lter such as the disk lter 4D (Figure 6) of absorbent materialmay be inserted around the plug, the lter being apertured at 42 toembrace the plug 26. The lter 48 is shown in position in Figure 3.

The bowl is preferably made of a suitable briar, but other material, ofcourse, may be used such as clay, meerschaum, corn-cob, etc., and thebowl holder is preferably of a light material such as aluminum. The bowlholder is also provided with a stem 44 comprising, for its majorintermediate portions, spaced stem or side members or portions 46 whichmerge adjacent the 4 bowl supporting portion as at 48 and at theopposite end as at 50.

A draw tube 52 shown in Figures 2 and 3 as being corrugated in a spiralshape, which in effeet provides a continuous Weir 53, is adapted to beinserted into the passage 54 of the bowl supporting portion`whichcommunicates with the trap 36. The end of the tube 52 extending into thepassage 54 is drawn down or tapered as at 56 Vand the size of thepassage 54 and tube is such as to provide a tight t. The tapered end 56prevents a whistle when the pipe is being smoked and greatly lessons thedanger of condensate running from the trap into the draw tube, and thecorrugated effect of the spiral of the drawtube not only providesprogressive traps but performs a cooling function.

The portion 50 is provided with the opening 58 for receiving the end 60of the bit 62 which may be a press, screw or other fit, the passage 54through the bit being preferably enlarged as at 66 to receive the end 68of the draw tube 52 which is preferably split a short way from the endas at 1D and is sprung or tightly tted into the passage 6B. The bit, ofcourse, is of any desired material, such as hard rubber, amber, Bakeliteand the like, and it is seen that in cleaning, the bit and tube may beremoved and replaced as a unit.

In Figure 4 a draw tube 'I2 is shown wherein separate corrugations 14are provided forming traps separated by separate weirs 15, the bowl end16 of said tube being drawn down or tapered as at 18, and the bit end 80being slit as at 82 for tightly fitting that end into the passage 66 ofthe .bit E2.

The tube as well as the bowl holder and stem is preferably of a lightweight metal such as aluminum, magnesium and the like.

In Figure 5 a plain draw tube 84 is shown having the drawn down ortapered end 86, similar to end 56, adapted to be received within thepassage 54. The opposite end 88 of the tube 84 is formed similarly tothe tube 52, being slit as at 58 for tightly tting said tube end intothe passage 66 in the bit 62.

It is to be understood that this application is not to be limited by theexact embodiments of the device shown, which are merely by way ofillustration and not limitation as various and other forms of the devicewill, of course, be apparent to those skilled in the art withoutdeparting from the spirit of the invention or the scope oi' the claims.
